Window solutions for modernisation under historical preservation requirements

… sound proofing and user and working comfort. Under historical preservation requirements, the external appearance could not be changed, not even by sun protection. The idea: One of the oldest and most proven window types, the casement window, was reinterpreted by the architects Dipl. Ing. Muus and Dipl. Ing. Wilde, who were in charge of the project. To solve these challenges, the architects worked closely with window manufacturer Sehlmann Fensterbau GmbH, glass manufacturer Semcoglas Holding GmbH and the window drive specialists from EMT and GEZE at an early stage of the project – true to the motto "Achieving more together". Commitment and open communication with everyone involved enabled us to recognise challenges at an early stage and develop solutions together. This close and very cooperative partnership helped ensure the project went smoothly. Architects Dipl.-Ing. Muus and Dipl.-Ing. Wilde, MUUS & WILDE Architektenpartnerschaft Hamburg The solution: modern double casement windows that comply with historical preservation requirements Dennis Bredahl from Semcoglas Holding GmbH optimised the thermal and sound proofing of the double casement windows with special solar control and thermal insulation glazing. © Jürgen Biniasch / GEZE GmbH A double casement window consists of two window elements arranged one behind the other and mounted on a common frame. The advantage of this historic window concept: The air space between the two window elements serves as thermal insulation and sound proofing, as the staggered opening of the windows means that sound has to pass through the space between them and is thus significantly attenuated once again, even during ventilation. Our modern casement window solution uses high-quality solar control glass on the outside and thermal insulation glass on the inside, which significantly improves the insulation value and sound proofing – also increasing user comfort in the buildings. Thanks to the double glazing, double casement windows already offer much higher thermal and sound proofing compared to conventional windows. These properties were significantly improved by the use of high-quality solar control glazing and thermal insulation glass as so-called neutral glass and a special coating (Semco Klimaglas). Dennis Bredahl, Semcoglas Holding GmbH Window manufacturers Jan and Lasse Sehlmann implemented customised solutions that combine historical preservation and user requirements. © Jürgen Biniasch / GEZE GmbH Pleasant indoor climate thanks to integrated shading The new double casement windows are equipped with an integrated shading system. This consists of automatic composite blinds with 35 mm wide slats that run between the two window frames. This solution makes it possible to keep the rooms cool during the day, while at the same time ensuring natural ventilation through the outer window. The blinds can be operated independently for added convenience. This reduces costs for air conditioners and the offices are naturally ventilated. Modern casement window at the Grindel tower blocks in Hamburg. © Jürgen Biniasch / GEZE GmbH Safety and ease of use thanks to modern window drives For the outer window leaves, GEZE Slimchain drives were installed as a system solution in combination with the Power lock locking drive , which enables simple operation via push buttons in the room. The inner leaves of the double casement windows can still be opened manually. The Power lock locking drive ensures that a reliable lock is guaranteed, especially on the higher storeys, and even under heavy wind loads. As only the outer windows are motorised, no additional protection is required for power-operated windows in accordance with the Machinery Directive 2006/42/EC. The opening drives were integrated into the window frame in a concealed location, and the supply lines were routed in the construction joint. A unique feature: With their very slim and discreet appearance, the Slimchain window drives integrate perfectly into the structure – so that strict historical protection requirements are met. This means the well-insulated double casement windows with integrated shade control are a modern, comfortable and energy-efficient solution that simultaneously respects the architectural character of the building and complies with the strict historical preservation requirements. The technical expertise and the rapid involvement of all parties in the planning process enabled us to develop customised solutions that meet both high historical preservation requirements and the needs of building users. Jan and Lasse Sehlmann, window fitters at Sehlmann Fensterbau GmbH Achieving our goal together: successful project planning and coordination GEZE was already in close contact with all project participants in the early planning phases, which enabled smooth discussions and effective collaboration. This early involvement of all parties made it possible to identify potential challenges at an early stage and develop solutions together. In addition, GEZE supported project coordination through continuous cooperation with the partner company EMT. Contact with the architect and building services was also maintained during the implementation phase. This ongoing collaboration ensured that all aspects of the project were seamlessly integrated and that the implementation went smoothly. Modern history: the listed Grindel tower blocks The Grindel tower blocks in Hamburg's Eimsbüttel district were the first residential tower blocks built in Germany after 1945. They were highly modern and comfortable flats when they were built in the post-war period, and remain so today – with central heating, hot and cold running water and lifts. In addition, the flats are bright and flooded with light thanks to their orientation and windows, while remaining pleasantly shaded in summer. Today, the ensemble of twelve high-rise buildings and a park is historically preserved. A tip for visitors to Hamburg: in the centre of the Grindel tower blocks is the Eimsbüttel district office, which has become a real tourist attraction with its historic paternoster lift The Grindel tower blocks in Hamburg's Eimsbüttel district were the first residential tower blocks built in Germany after 1945. © Jürgen Biniasch / GEZE GmbH These consist of two window elements arranged one behind the other and mounted on a common frame. © Jürgen Biniasch / GEZE GmbH Double casement windows were used as a customised window solution for the Grindel tower blocks. © Jürgen Biniasch / GEZE GmbH Comprehensive support throughout the entire project life cycle Our experts support you throughout the entire project life cycle – from planning and project coordination to the certified assembly and initial acceptance of GEZE systems and regular maintenance, through to retrofitting and dismantling.

Door planning – handling complex demands with GEZE

… Sound insulation usually needs heavy doors with multiple sealing levels. Often, such doors are not barrier-free because of this, as opening and closing them takes a large amount of force. Or smoke and heat extraction system fresh air versus fire and smoke protection: While smoke and heat extraction systems open doors, fire and smoke protection needs closed doors. There is also a seeming contradiction between 'fire protection and accessibility”' In some cases, expert planners are called on to reconcile contradictory needs and functions. Door lists for systematic door planning Door lists have become an established practice for door planning in large building projects. These include precise information on the location, installation situation, geometry, material properties, design and necessary technical equipment for each individual door. Door lists describe all significant properties and specifications; these do not apply to all doors in the building project, but rather differ from door to door. These include, in particular: Dimensions, including opening width, opening direction (left hand door or right hand door). Specialised needs, such as sound insulation, fire protection, escape route, burglar protection, radiation protection or climate class Material, surfaces and the design of the door leaf and frame Details on the lock and door fittings, as well as additional components like door closers, hold-open systems or door automation. Door lists can be used to systematically record all features. But beware: this tool doesn't help with the feasibility of implementing the doors in the context of the building. Here too, experienced door planners come into play. Expert door planning is a complex task, and is inseparable from expert planning of other product groups. Such interfaces have to be defined early on. Günther Weizenhöfer, Team Leader of Pre Sales Development Effective door planning with BIM BIM makes complex construction projects more cost-effective and efficient © Getty Images/iStockphoto Building Information Modeling (BIM) is the future for digital and interdisciplinary collaboration. BIM allows all the product groups to work together in one digital model, a digital twin, and use all data together. Everyone involved in the building life cycle benefits from this: from the investor, architect or expert planner, to the installation engineer, system producers and product manufacturers. BIM is also ideal in expert door planning. Prompt coordination with expert planners in other product groups is the key to translating all the demands into practical functions. In addition, this allows everything to be planned efficiently, key information to be linked and functions to be tested in the context of the entire building technology before they are implemented in practice. Last but not least, it also facilitates precise predictions for the construction and life cycle costs of a building right from the start of the building plan . We have developed BIM door objects as an extremely useful tool for expert door planning. They are based on results from the work of the door group at buildingSMART . In addition, we have compared a wide range of existing meta data with official door lists. As a result, our BIM objects are also perfectly suited to international projects.

Smart building: Intelligent Development Centre

… sound absorption concept down to the smallest details acoustically decouples areas for meetings, walkways and individual desks. Touch panels for central operation Simple touch panel operation. © GEZE GmbH The open-plan office offers short communication channels and comfortable 'agile' work thanks to the flexible workstation units. An ingenious sound absorption concept designed down to the smallest details acoustically decouples areas for meetings, walkways and individual desks. Meeting corners or separate areas can be created for highly concentrated work in a quiet environment, while lighting and the indoor climate can be controlled by zones. The smart sliding shutters in front of the windows are activated depending on the light or solar radiation. Doors are automatically opened and locked at certain times of the day. At the end of working day, an automatic night-time closer is triggered. Find more information about building safety Central operation and monitoring with GEZE Cockpit There are hardly any push-button switches in the building. All product groups and elements of the room technology are visualised centrally on a single interface and can be monitored at a glance. Product group statuses are controlled and displayed either automatically on the basis of predefined scenarios, or by the employees themselves, of course, via touch panels. The indoor climate, media technology, lights, windows or doors can be controlled via a control panel by clicking on icons. The newly developed GEZE Cockpit building automation system makes all this possible. Its tasks and unique advantages are central visualisation, monitoring and operation of all integrated products. GEZE Cockpit also permits authorised users to activate the product groups and display their status, and have special authorisations via their PCs. Laboratory for smart possibilities There is nothing more obvious than using the smart development building for your own testing and learning. It will enable to us to answer questions such as what makes a building 'truly' smart, which networking applications bring the greatest increase in comfort, security and energy efficiency, and what networked features are needed in the building of tomorrow. It also offers the best conditions for testing the interoperability of smart GEZE products and other product groups under real conditions, i.e. with the people who work there daily. The intelligent building allows flexible grouping and the addition or replacement of products, so that new networking solutions can be tried and tested over and over again. The insights gained are used to continually develop the intelligence of all smart GEZE products and expand and roll out the benefits for users with the aid of GEZE Cockpit. The building automation system can be operated as an independent system, or integrated with the BACnet and KNX communication standards in an overarching building control system. Data communication between GEZE Cockpit and the integrated products and systems takes place via interface modules. In addition to the visualisation of all integrated products in a central location, the smart system offers a unique added value: for the first time, it is possible to incorporate the complete intelligence of GEZE products - i.e. all available control options and status information - into the building network. Doors and windows can thus be controlled and monitored with the highest degree of precision. Examples include the exact knowledge of the status of a door or a window, the value of a sensor, or feedback from a command that has been executed and alarm messages. GEZE Cockpit offers many other benefits: increased building security, predictive maintenance and efficient building management. Increased security and short distances through smart networking With more than one hundred multifunctional doors and windows integrated into the building management system, building managers are always aware of the status of each door or window. You can centrally open or close them as needed, change the operating mode of a door and be sure that all elements in the building shell are locked or bolted. Time-consuming inspection rounds are eliminated. Commands can be issued for single, multiple or all doors (central locking). Individual door-scenarios can be saved in GEZE Cockpit, so that doors can be automatically opened, closed or locked as controlled either by time or triggered by an event. All processes on a door - and therefore also irregularities - are reported back. Whatever happens at a door, immediate action can be taken. Find out more about automatic doors 'Climate goals' for pleasant and smart working Various scenarios, e.g. the 'climate-active façade' and the 'preconditioning' of rooms are currently being tested in the smart building in connection with GEZE Cockpit. Optimal air quality is essential for a pleasant office environment. Meeting rooms should be ventilated again ahead of use. Scenarios created in the building management system ensure intelligent, energy-efficient interaction between product groups. The smart façade technology responds automatically to changes in the external climatic conditions. The blind is lowered automatically when there is solar radiation. Smart windows open or close depending on the outside temperature. The centrally controlled automatically night-time cooling down of devices has already created a good indoor climate at the beginning of the day. In this scenario, the IQ windowdrive range of RWA drives and GEZE's Powerturn swing door operators, presence, location, air quality and temperature sensors, heating, ventilation and the air conditioning system, lighting and shading and the room occupancy system interact with each other to control the windows and ventilation flaps and the fresh air doors. Smart bodyguards on automated windows Window safety system as intelligent sensor solutions in the building bus secure the windows integrated into the building management system in all generally accessible building areas. The intelligence remains 'local' because the information from the safety sensors takes precedence. Ventilation will be delayed or stopped if there is an obstacle in the window opening such as a hand and closing operations have already been initiated by the building regulation due to sensor information (rain, wind or temperature). More information about window safety systems Optimum climate: Smart Actuators control each other GEZE is also testing a very unique combination of air conditioning, window drives and weather sensors. The smart actuators control each other depending on the sensors' data. For a highly efficient and energy-saving air conditioning, the performance of the air conditioning system is intended to automatically adapt to the exact opening width of a window. A constant balance between the outside and the preset room ambient temperature for climate control in the individual room zones on each building level is also tested by the interaction of heating, ventilation and air conditioning. When programming the scenarios, physical parameters such as the size and position of a room in the building have been taken into account thoroughly via the building management system.
